Description
161 R NV UInt 0-32767
Log Buffer Wrap / Missed Log Counter. In continuous mode, this counter increments each time the
internal circular log buffer wraps and overwrites old data. The total number of logged entries since the
last log reset is: (Register 161 x 5760) + Register 163. In single shot mode this counter is the number of
log entries lost due to the buffer being full. The counter is cleared on logging reset.
162 R NV UInt 0-32767
Max Number of Logging Days. Based on the Sub-Interval Length and the depth of the log buffer, this
register shows the maximum number of days that data will be logged following a reset until the Buffer is
full (Single Shot Mode) or overwrites old data (Continuous).
163 R NV UInt 0-32767
Number of Logged Entries since the log buffer wrapped or was reset. In single shot mode, this is the
total number of valid entries in the buffer. Any entries beyond this will read back as QNAN (0x8000).

Log Register Selection – Write the number of the 16 bit register to be
logged. To log a 32 bit value (such as accumulators and oating point
values) two log registers must be used, one each for the most and least
signicant register (MSR & LSR).
